Changes in children’s attachment security to mother and father after the birth of a sibling: Risk and resilience in the family

Changes in children’s attachment security to mother and father were examined for 230 firstborn children (M = 31.17 months), their mothers and fathers participating in a longitudinal investigation starting in the last trimester of the mothers’ pregnancy and 1, 4, 8, and 12 months after the birth of an infant sibling. Both parents completed the Attachment Q-set at prenatal, 4, and 12 months. Growth mixture models revealed four latent classes in which children’s attachments were (a) both secure with a modest decline to both parents (68.3%); (b) more secure with father than mother with a steep decline for both (12.6%); (c) both insecure with no change (10%); and (d) more secure with mother than father with a modest increase for both (9.1%). Multi-group latent growth curve analyses revealed that parenting and coparenting differed across families. Children had lower externalizing behavior problems in families with two secure attachments than in families with one secure attachment, either to mother or to father, who, in turn, had fewer problems than children with two insecure attachments. Findings underscore the strengths of a family systems framework to understand attachment relationships with multiple caregivers and the family risks and protective factors that covary with children’s behavioral adjustment after the birth of a sibling.

Leveraging telehealth to evaluate infants with prodromal autism spectrum disorder characteristics using the telehealth evaluation of development for infants

This study investigated the feasibility of recruiting and assessing infants with prodromal autism characteristics in the first year of life via telehealth. Participants included 41 infants (Mage = 10.51 months, 51.2% female, 80.5% White) whose parents had concerns about social communication delays or autism. All infants met concerns criteria on a social communication screener. Infants were subsequently assessed via telehealth using the Telehealth Evaluation of Development for Infants protocol, wherein parents are coached through a series of semi-structured interactions from which key measures of autism characteristics, communication, developmental level, and clinical best estimates of autism spectrum disorder likelihood are scored. Parents completed online questionnaires and surveys measuring the acceptability of the telehealth visits. Across both parent report and examiner-derived measures, infants demonstrated high scores on measures of purported autism traits, decreased communication skills, and delayed achievement of developmental milestones. Caregivers’ acceptability ratings were uniformly positive. Results highlight the potential for telehealth to expand the scope of studies of emerging autism beyond infant sibling designs and to increase families’ access to early evaluation services. Lay abstract Many families seeking early evaluations for autism spectrum disorder face long waitlists, must often travel to centers with appropriate expertise, and are frequently told by providers to “wait and see.” This results in significant stress for families and delayed supports to infants and their caregivers who could benefit. This study evaluated whether telehealth could be used to identify and evaluate infants with early autism spectrum disorder characteristics in the first year of life. In this study, we evaluated 41 infants via telehealth using a standard set of probes and scored behavior related to social communication, play, imitation, and other developmental domains. We found the majority of infants demonstrated elevated likelihood of autism spectrum disorder on both parent-reported questionnaires and examiner-rated behavior. Caregiver ratings of the overall utility of the protocol used in this study were high. Overall, this study demonstrates the feasibility for telehealth-based approaches to evaluate infants’ with elevated likelihood of autism spectrum disorder in the first year of life, which could help to improve families’ access to care and to expand our capacity to conduct studies evaluating possible intervention supports.

Maternal and paternal trajectories of depressive symptoms predict family risk and children's emotional and behavioral problems after the birth of a sibling

The current study examined trajectories of maternal and paternal depression in the year following the birth of an infant sibling, and relations with family risk factors and firstborn children's internalizing and externalizing behavior problems. Latent class growth analysis was conducted on 231 families in a longitudinal investigation (prebirth and 1, 4, 8, and 12 months postbirth) and revealed four classes of families: both mother and father low in depressive symptoms (40.7%); mother high–father low (25.1%); father high–mother low (24.7%), and both mother and father high (9.5%). Families with both mothers and fathers high on depressive symptoms were higher on marital negativity, parenting stress, and children's internalizing and externalizing problems, and lower on marital positivity and parental efficacy than other classes. Children, parents, and marital relationships were more problematic in families with fathers higher on depressive symptoms than in families in which mothers were higher, indicating the significant role of paternal support for firstborn children undergoing the transition to siblinghood. Maternal and paternal depression covaried with an accumulation of family risks over time, no doubt increasing the likelihood of children's problematic adjustment after the birth of their infant sibling.

Prelinguistic gesture use in mother-infant and mother-infant-sibling interactions

I tested the hypothesis that, in infant-mother-sibling interactions, infants with older siblings aged 11 to 24 months produce deictic gestures when they are proximal to, or engaging in joint attention with, their mothers more frequently than same-aged infants without siblings. Fifteen infant-mother dyads and 10 infant-mother-sibling triads were individually observed for 15 minutes in a playroom full of toys. Infants involved in infant-mother-sibling interactions produced more deictic gestures when they were proximal to their mothers than infants in infant-mother interactions. Further, infants involved in infant-mother-sibling interactions accompanied their gestures with vocalizations at a higher rate than infants in infant-mother interactions. This result suggests that infants with older siblings monitor their mothers more carefully in interactions in which their sibling is also present, and that they produce deictic gestures in order to effectively elicit joint action with their mothers.
